VALVE.

SPECIFICATION forming part of Letters Patent N0. 785,594, dated March21, 1905.

Application filed Ncvcmhc; 11, 1904:. Serial No. 232,340.

To (all whom, 7125 may concern:

Be it known that I, CLARENCE GEARI-IART CRISPIN, a citizen of the UnitedStates, residing at Berwick, in the county of Columbia and State ofPennsylvania, have invented new and useful Improvements in Valves, ofwhich the following is a specification.

My invention relates to improvements in that class of valves especiallyapplicable or serviceable for water mains or pipes.

It has for its object to provide for venting such water mains or pipesorthe release of confined air when admitting water thereto; also, for theadmission of air thereinto when the water is withdrawn or otherwiseescapes therefrom, and to carry out these ends in a simple and effectivemanner.

Said invention therefore consists of certain structural features,substantially as hereinafter more fully disclosed, and particularlypointed out by the claims.

In the accompanying drawings, illustrat ing the preferred embodiment ofmy invention, Figure 1 is a side elevation thereof." Fig. 2 is avertical central section of the same. Fig. 3 is a horizontal sectionproduced therethrough upon the lines 3 3 of Fig. 1, and Fig. 4 is a likesection taken through the upper row of air-vent openings in the extremeupper end of the device.

In the carrying out of my invention I suitably inclose or house withinthe principal cylindric member or casing 1 a spherical member or ball 2,forming the valve proper. Said cylindric member comprises two sections 11 each having inward from an annular flange or extension 1 ascrew-threaded surface engaged by a correspondingly-screwtl readedsleeve or coupling member 1 con necting or coupling together saidsections, as at 1. As the sleeve or coupling member 1 is screwed to'itsmaximum limit uponsaid member sectionsl 1 it will be noted that theflanges 1 of the latter serve as stops and abut the ends of saidcoupling or sleeve member, serving to effectively assemble the parts.

The casing member lower section 1 has a downward tubular extension 1whose exterior has thereon an angular or nut formation 1 forconvenience, as in applying a wrench thereto to secure the device inposition upon the pipe or water-main. I Below said angular or nutformation 1 said tubular extension 1 has produced also upon its exteriora screwthread 1 to render effective its connection with the pipe orwater-main, as will be apparent. Y

The casing member upper section 1 has in continuation of its innersurface also a downward extension or wall 1 of relatively greatlyreduced cross-section, with its extreme lower portion offset, the innersurface of the latter being provided with a screwthread, as at 1, thepurpose of which will later appear. Said downward extension or wall 1 isprovided with a plurality of orifices or openings 1, whose office willbe presently seen.

A cup or receptacle member 3 is arranged within the chamber formed bythe parts 1 and 1 within which rests initially the ball or valve proper,2, and has its outer surface, near the upper edge, screw-threaded, as at3 to engage with the screw-threaded surface 1 of the offset 1 of thewall or downward extension 1 to effect connection therebetween and theconsequent suspension or sup port of said cup member in position. Saidcup or receptacle member 3 thus forms, with the wall 1 the inner surfaceof the sleeve 1 and the inner surfaces of the casing member upper andlower sections 1 1 a chamber within a chamber, (designated as 4 4respectively,) corresponding surface of said lower section beingsuitably removed or spaced off from said wall and cup or receptaclemember for that purpose. In the bottom of said cup member of the innerchamber 4 is a water passage or opening 5, the purpose otherwise ofwhich will be presently apparent. Said casing member upper section hasan upward tubular extension 1 and upon the latter is screwed a cap 6,said extension having numerous air orifices or'holes 1 and said cap havving also orifices 6 in continuation of and registering with the upper ofsaid holes 1 for venting purposes.

As air is forced ahead of water entering the main or pipe to which saidvalve may be applied said air passes upward through the tu- Too bularextension or neck 1 and entering the outer chamber 4* and passing by thevalved or closed passage or water way 5 passes through the orifice 1 andinto the inner chamber 4 and escapes through the orifice or openings 1 6in the upward extension 1 and cap 6 for obvious purposes. It is notedthat the extent of the air-pressure exerted at the water-passage 5.isinappreciable in its effect upon the valve 2. Therefore said passagewill accordingly remain closed against the escape of air at that pointinto the inner chamber 4. Again, when the water rises into thevalve-casing the water will pass through the opening 5 and en age andforce by its continued ingress at that point the valve 2 to its seat, asat 2 in the upper inner surface of the chamber 4, and thus prevent orcut off the escape of said water through the orifices or vents 1Latitude is allowed as to details herein, as they may be changed ascircumstances suggest without departing from the spirit of my invention.

I claim 1. A device ofv the character described, having a chamber withina chamber, and a valve initially closing a port or opening in the lowerportion of the inner chamber, the outer chamber having communicationwith said inner chamber, at a point above said valve.

2. A device of the character described, having a chamber within achamber, and a valve initially closing a port or opening in the lowerportion of the inner chamber, the outer chamber communicating with theinner chamber at a point above said valve, said inner chamber havingair-egress openin s or outlets also arranged above said va ve.

3. A device of the character described, having a chamber within achamber, and a valve initially closing a port or opening in the lowerportion of the inner chamber; the

outer chamber having openings communicating with the inner chamber at apoint above said valve, and said inner chamber having a seat in itsupper portion to receive said valve when removed from over the port oropening initially closed thereby.

4. A device of the character described comprising upper and lowercasing-sections, a 0 51011 said upper section having a downwardextension, in continuation of its'inner surface, provided with orificesor openings, a cup-like member connected to said downward extension andhaving a bottom opening, said coupling member having its inner surfacespaced off or offset from said downward extension and cup-like member,and a valve initially closing said bottom opening, said upper sectionadapted to form at its inner upper end a seat for said valve when thelatter is lifted from its initial position.

5. A device of the character described, employing two casing-sectionscoupled together by a cylindric or connecting member, the upper sectionhaving a downward extension, in continuation of its inner surface,provided with orifices or openings, said upper section also having anupward capped tubular extension also provided with orifices or openings,a cup-like member connected to said downward extension and having a bottom opening or port, said coupling member having its inner surfacespaced off, or offset from said downward extension and cup-like member,and a valve or ball initially closing said bottom opening, said uppersection adapted to form at its inner upper end a seat for said valvewhen the latter is lifted from its initial position.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.
